Hello,
I would like make a project with an arduino.
In this project, we use a WS2801 rgb led module breakout => http://blogs.iad.zhdk.ch/color-light-hs … -rgb-leds/
But this module is replace by the WS2812 rgb led… and low cost .
For WS2801, I have 4-pin connection on my arduino :
5V → 5V
SDI → PIN2
CKI → PIN3
GND → GND
For WS2801, just 3 : https://cdn.sparkfun.com/assets/5/7/c/3 … 000001.png
5V → 5V
DI → PIN2
GND → GND
But my question is: What is differences for code? How adapt code?
Thanks for your helps.
I’m French, sorry for my english !
